jenkins持續集成 - mavem構建spring項目打包發佈到tomcat

jenkins持續集成 - mavem構建spring項目打包發佈到tomcat

準備工作
jenkins持續集成 - docker-compose 搭建jenkins服務
jenkins持續集成 - 配置JDK
jenkins持續集成 - 配置git
jenkins持續集成 - 配置maven
jenkins持續集成 - jenkins插件線安裝

默認準備工作完成（上面教程我會陸續補全）

背景交代，jenkins服務是用docker搭建的，tomcat服務也是用docker搭建的，docker是在哪個平臺搭建的不重要，本實例是由centos7搭建，並且jenkins和tomcat分別在兩臺機器上，這會涉及跨域問題下面會說到，有坑！

沒有maven選項的需要安裝maven插件
jenkins持續集成 - 安裝maven插件

然後
添加項目託管地址

配置maven構建

然後就可以測試一下能否構建成功

正在下載maven

這裏如果太慢的話，看這個文章後半部分
jenkins持續集成 - 配置maven

然後重新構建

構建成功，查看一下

構建成功，已經成功了一半了，加油！
接下來就是要把打好的war包發送到tomcat容器（2020年 3月31日 星期二 00時16分45秒 CST，晚安，明天繼續）

繼續～～～

發佈到tomcat又需要下載插件，下面沒有我們需要的，下載插件 Deploy to container，安裝插件方法參照jenkins持續集成 - jenkins插件線安裝
安裝好插件

配置tomcat

WAR/EAR files war包的位置
**/*.war 這個是通配符配置war包位置，可以寫成確切的位置 target/spring-mvc-xml.war(如下圖)
Context path 官方的解釋：容器應用於發佈WAR/EAR的上下文路徑。請注意，如果要部署的WAR/EAR內部嵌入了容器特定的配置，則可能會覆蓋此選項。 其實就是項目名

配置tomcat用戶名密碼，找到自己的tomcat，進入conf文件夾，修改 tomcat-users.xml

<role rolename="manager-gui"/>
  <role rolename="manager-status"/>
  <role rolename="manager-script"/>
  <user username="tomcat" password="tomcat" roles="manager-gui, mananger-status,manager-script"/>

配置好，可以構建了，然後你可能會發現

這個看起來是權限問題，我們用戶已經配置過了，而且權限看起來沒有問題，

查來查去，可能是跨域問題，修改**…/webapps/manager/META-INF/context.xml**文件，我們允許所有地址的請求（生產中可不能這麼玩，要配置指定ip）

<Context antiResourceLocking="false" privileged="true" >
  <Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="^.*$" />
</Context>

問題總結

允許所有地址訪問manager status頁面
由於我使用虛擬機部署Tomcat，本機訪問，所以是兩個不同的ip地址進行訪問，那麼原來的配置文件中只允許我127.0.0.1進行訪問，所有我在本地訪問時則會報403

重新構建,查看日誌

構建成功，我們查看一下

恭喜你！成功！cool！ cool！

靜下心來慢慢走，不知不覺走就走了很遠，加油！

接下來會寫，maven定時構建，當我們提交代碼後，jenkins定時檢查代碼是否有更新，有更新的話，自動構建打包發送tomcat，把我們把繁瑣的打包部署過程自動完成，我們只需要專心寫代碼就OK了，想想就爽！cool！cool！
